Telerik.Web.MVC Extensions

Hi,

We are looking to upgrade your application. Currently it uses:

Telerik.Web.Mvc Version 2011.3.1115.235 (Extensions) 

Telerik.Web.UI Version 2013.3.114.35 (Telerik RadControls for ASP.NET Ajax)

The Telerik ASP.Net Ajax I can update using the Wizard tool however the Telerik.Web.Mvc Extensions is no longer supported. 

I am wondering what is the best way to replace it with the current Telerik standard?

Thanks,
